How Is A-RB Done?

The corrosion resistant component of Stainless Steel is Chromium. The higher the Chromium content of the Stainless Steel, the higher the corrosion resistance. However, Chromium is the softest component of the Stainless Steel. This means, the higher the Chromium content, the less durable and less smooth the bearing will be.
 
Shimano’s goal was to maintain the hardness, durability and smoothness of our bearings while drastically increasing the corrosion resistance. To do this, after machining, the presence of Chromium is concentrated to the surfaces of the bearing. This makes the outer surfaces of the bearing extremely corrosion resistant, while maintaining the hardness of the Stainless Steel. The end result is a bearing that is at least 10 times more corrosion resistant than standard Stainless Steel bearings.

Corrosion Comparison
  • At least 10 times more corrosion resistant than standardstainless steel ball bearings.
  • Easy Maintenance-no shield design allows for easy flushing of debris and easy lubrication.
  • A-RB bearings are made of stainless steel that has been through the A-RB process.
  • Increased Bearing Speed-no shield design and lighter viscosity lubrication reduce friction and allow the bearing to spin faster and longer.
  • A-RB Bearings are the result of S–Concept: Smooth, Silent, and Strong.
